The academic effectiveness of a bridging year for commerce undergraduates

Human resources development in South Africa is constrained by the underpreparedness of many students for university. The problem is particularly acute among school leavers for whom English is not their first language and who are thereby at a disadvantage in an English language university. In order to address the problem, which goes beyond language, bridging curricula have been devised. This research analyses how effective one such intervention is, in terms of an academic achievement outcome.

Decisions to allocate resources to bridging intervention need the assurance that the resources are used effectively. An ex post facto experimental research design ts used in this study to test the learning outcome of the PBS bridging intervention. The analysis assesses whether the PBS programme increases the academic achievement of students at first‐year level.

The examination results achieved by an experimental group of PBS students who matriculated from DET schools are compared with the results of a control group of DET matriculants. The research shows that the academic achievements of the PBS group during the bridging year were superior to those of the control group. Furthermore, superior performance was sustained by the PBS students after they Joined the mainstream BCom curriculum. After the bridging intervention, the PBS students achieved 7.7 percentage points better in Business Economics I examinations than the control group. The research design controls for demonstrated academic ability at school At a 0.01 level of statistical significance, the results of the analysis indicate that the PBS intervention has contributed positively to the students’ academic achievement.     

Bicycle-related injuries: Injury,hazard, and risk patterns

Abstract

This paper provides the results of a U.S. Consumer Product Safety Commission (CPSC) study to determine the circumstances involved in bicycle-related injuries treated in U.S. hospital emergency rooms. It also includes information from a CPSC exposure survey of the U.S. population of bicycle users and their patterns of bicycle and helmet use. Together, these data were used to identify and evaluate risk factors currently associated with bicycle use in the United States

Risk models identified factors specifically associated with injuries to children and to adults. Children were at particular risk of injury, and appeared to be especially vulnerable to head injury. In addition, the risk of injury for children was significantly increased when riding in non-daylight conditions. For both adults and children, there was a higher risk of injury on streets than in such areas as bike paths or unpaved surfaces. While some problems associated with bicycle assembly, operation, and maintenance were observed, the data did not suggest that any mechanical remedy is likely to reduce injuries substantially.     

Are multiple labels on food products beneficial or simply ignored?

This study examines consumer preferences and willingness to pay (WTP) for organic wheat products exhibiting single labels, as well as multiple labels, including organic. The additional labels considered are related to the organic label (non-genetically modified organism [non-GMO]) or perceived as health-promoting (gluten-free, low-carb, sugar-free). Study data were collected using a consumer survey conducted online in 2017 across 16 U.S. western states and analyzed using random parameter logit models. Findings show that organic-labeled wheat products with additional claims were valued equally or less than the organic only version. Overall, consumer higher objective and subjective knowledge of organic standards, as well as preferences for gluten-free products, increased their WTP for organic wheat products. Consumers unfamiliar with organic standards valued the non-GMO label over the organic label. Additionally, consumer WTP for health-related claims on hedonistic products was low or even negative. Hence, multiple labels on organic products generally provide no additional consumer benefit and are likely ignored. Study findings suggest that using the claim that most distinguishes the product, or is most salient, may improve product pricing. Also, non-GMO certification rather than organic certification should be considered for some markets. Finally, consumers with preferences for gluten-free products represent a potential market for organic wheat products.     

Land tenure, population pressure, and deforestation in Haiti: The case of Forêt des Pins Reserve

Haiti, with a forest cover estimated at 3% of all land area, has experienced severe degradation of its natural resources and a significant change in its land cover. While deforestation in Haiti is obviously multifaceted, one issue emerges from previous empirical analysis in explaining deforestation: land tenure. This study focuses on the causes of deforestation in Haiti, particularly in Forêt des Pins Reserve, using the annual average area of cleared forest per household as the dependent variable. Data were collected with the use of a survey instrument administered to 243 farm households in 15 villages inside the Reserve. Tobit Regression results reveal that household size, education of head of the household, land tenure regime, and farm labor are important factors affecting land clearing.     

Do the Right Thing: The Imprinting of Deonance at the Upper Echelons

This study expands the application of deonance theory into organizations’ upper echelons by examining how CEOs imprinted with a sense of duty can influence managerial decision-making. We hypothesize an imprint of bounded autonomy, an ought-force that constrains their decision-making and understanding of behavioral freedom, influences duty-bound CEOs to self-report errors in past financial reporting. We test deonance theory propositions of instrumentality for behavioral expansion, namely loss avoidance and gain attainment, related to institutional ownership concentration and CEO equity ownership. We use CEOs that are graduates of U.S. service academies as a proxy for duty-bound executives and find firms they lead are more likely to issue a financial restatement to correct a previous reporting error. This finding is robust to alternate explanations such as being error-prone, earnings management, auditor oversight, and risk behaviors. We also find evidence that deonance may be subject to behavioral expansion. The likelihood of issuing a restatement decreases as institutional ownership concentration and CEO equity ownership increases. This study shows imprinted deonance within the C-suite influences important organizational outcomes.

     

Use of a validated algorithm to estimate the annual cost of effective biologic treatment for rheumatoid arthritis

Objectives:

To estimate biologic cost per effectively treated patient with rheumatoid arthritis (RA) using a claims-based algorithm for effectiveness.

Methods:

Patients with RA aged 18–63 years in the IMS PharMetrics Plus database were categorized as effectively treated if they met all six criteria: (1) a medication possession ratio ≥80% (subcutaneous) or at least as many infusions as specified in US labeling (intravenous); (2) no biologic dose increase; (3) no biologic switch; (4) no new non-biologic disease-modifying anti-rheumatic drug; (5) no new or increased oral glucocorticoid; and (6) ≤1 glucocorticoid injection. Biologic cost per effectively treated patient was defined as total cost of the index biologic (drug plus intravenous administration) divided by the number of patients categorized by the algorithm as effectively treated. Similar methods were used for the index biologic in the second year and for a second biologic after a switch.

Results:

Rates that the index biologic was categorized as effective in the first year were 31.0% etanercept (2243/7247), 28.6% adalimumab (1426/4991), 28.6% abatacept (332/1160), 27.2% golimumab (71/261), and 20.2% infliximab (474/2352). Mean biologic cost per effectively treated patient, per the algorithm, was $50,141 etanercept, $53,386 golimumab, $56,942 adalimumab, $73,516 abatacept, and $114,089 infliximab. Biologic cost per effectively treated patient, using this algorithm, was lower for patients who continued the index biologic in the second year and higher after switching.

Conclusions:

When a claims-based algorithm was applied to a large commercial claims database, etanercept was categorized as the most effective and had the lowest estimated 1-year biologic cost per effectively treated patient. This proxy for effectiveness from claims databases was validated against a clinical effectiveness scale, but analyses of the second year or the year after a biologic switch were not included in the validation. Costs of other medications were not included in cost calculations.     

For Leaders to be Transformational,They Must Think Imaginatively

In the current article, it is argued that individual differences in imaginative thinking may predict transformational leadership. Transformational leaders create a vision for the future, which they must imagine. Moreover, being able to imagine differences in thinking and behavior may aid in the development of more transformation leaders via guided reflection on their leadership practices. Ultimately, assessment of individual differences in imaginative thinking may be useful in recruitment of leaders.
